Yeah, and with nothing new being posted each time they stop in, eventually they will just stop coming around. Which most certainly is already happening.
I went through the same thing with the ArmsLocker.com website I used to own. When the number of members signing in per day dropped below 10, someone offered to buy it from me just before I was going to pull the plug anyway. That site never did bounce back, so the guy definitely got the short end on that deal.
Best I can tell, this site is in a death spiral now.
Not enough people posting to sustain the interest of the rest of the people who are just lurking. So not enough people reply to those posts that someone DOES make, so they just stop posting completely as being a waste of their time and effort.
Oh well...........
